David Moyes' men overturned a 2-0 deficit and odds of 7/4 to oust Olympiacos 3-2 on aggregate, keeping their final hopes of a trophy alive amid what has otherwise been a miserable campaign.

Bayern Munich are considered the side to avoid in Friday's draw as 15/8 favourites, followed by Barcelona and Real Madrid (both 4/1), while the Premier League's other representatives, Chelsea, are 12/1.

Sky Bet's Head of Football Trading Paul Wiggins said: "It was enough on the night for United but it was a tie we initially expected them to cruise through, having made them 1/6 to qualify before the first leg.

"The comfortable nature by which the other seven sides came through coupled with United's domestic troubles makes it impossible for us to consider them amongst the favourites, but they are actually the biggest liability in our outright book having been backed at as long as 50/1."
